openvp install via apt-get hangs indefinitely

[LukeBMay]

Ubuntu 17.10 fresh install

sudo apt-get install openvpn

The above command causes an indefinite terminal hang. And I have to manually kill processes to get apt working again.

Here are the errors I receive after killing `sudo kill -9` processes with `openvpn` in the name:

   invoke-rc.d: initscript openvpn, action "cond-restart" failed.
   Created symlink /etc/systemd/system/multi-user.target.wants/openvpn.service → /lib/systemd/system/openvpn.service.
   W: APT had planned for dpkg to do more than it reported back (30 vs 34).

Thanks for taking the time to file this bug!

This bug was reported against openvpn in Ubuntu 17.10 which is not supported anymore. I was not able to reproduce this issue in 18.04 (LTS version after 17.10), so I am marking it as Invalid.
